igure 1 is a plan of my improved form of connector.

Fig. 2 is a partial sectional view of the connector taken on thebroken line 'A-A of 1.

Fig. 3 is a cross section of the connector 1 with a storage battery plate post fastened in the connector.

Figs. 4 and 5 are top. and side views respectively of a difierent type of terminal embodying my invention.

Fig. 6 is a plan view of'the nut shown in The adapter has a sleeve portion 1 having an inner conical socket 2 and an interior screw 3 with the head 4- cast in the closed This screw is preferably brass or some other material that ossessesmore strength rojecting substantially the sleeve portion is an is adapted to fit over the plate post. A cable 6 is cast or otherwise terminal member 7 of brass which is adapted to fit into the socket 2 andthread onto the screw 3.

he manner in which 0 connector will be assembled will now be described. After the plates have been laced in the cell and the cell nished, the terminal 7 of the cable 6 is placed in the socket 2 of the adapter 1 and the latter is rotated to thread the screw into the terminal. When the two parts have been drawn sufficiently together by meahs of the screw, the eye 5 of the adapter is then laced over the plate post 8 as shown in ig. 3. The nut 9 is then screwed down. on

screw 10 which has been previously cast in the plate post 8.

h1s improved form of adapter has a very neat appearance, and since the brass screw is entirely surrounded by non-corrodible hard lead, a very perfect union of low resistance is formed. The connection is also of such construction that the cable terminal 7 cannot be accidentally adapter, especially if it verse twist to maintain in the tightening direction after the adapter is clamped in position.

. y improved cable connection is not limited in its application to any particular is given a slight reofgpplymg the cable to an adapter as shown igs. l and 2, I may use it in connection with a construction such as is shown in Figs. 4: and 5 for example. In these figures the terminal is screwed into the cable in the same way as previously described,- but the connection difi'ers from the other modifications in that it has a lug or eye 11 adapted to be fitted to a plate post or to any other member.

In Figs. 3 and 6 I have shown a special form of iiut for clamping the adapter to the plate post. This consists of a flange or washer 12 integrally joined to thumb members 13 which may be conveniently gripped to screw down orunscrew the connection.

aving described claim is:

'1. In storage batteries, a plate post, an adapter having a In with an opening to fit over said post an? having a socket portion integral with said lug and closed at one end, ascrew having its head secured in the closed end of the socket and a cable terminal fitting in said socket, said terminal having a threaded opening adapted to co-' operate with saidscrew to draw the terminal into the socket when theadapter is rotated relative to the terminal. j

2. In storage batteries, a plate post, an adapter having a lug with an opening, to fit over said post and having an integral socket member closed at one end, a terminal member fitting in said socket and a screw having 100 f storage battery connection. Instead my invention, what I jarred loose from the a twisting moment I g I 1,376,1Q3

one end secured in one of said members, the other member having a threaded opening adapted tocooperate. with said screw to draw the terminal member into the socket member.

3. Astorage batter; terminal comprising 9. lug having an openm adapted to fit over a plate gost, and a soc et-portion' integral with sai lug and losed at one end, the ottom of such integral socketportion carrying 10 threaded means-adapted to cooperate with threaded means on a terminal member fitting in such socket, so as to draw said terminal member into said socket member.

In testimony whereof I hereunto affix my 15 signature.
